摘要: The aim of the present study was to investigate electrochemical formation active chlorine and its subsequent use for degradation pesticide fenobucarb. Initially, process production investigated using an flow-cell with a Ti/RuO2 plate electrode. contribution four main factors (chloride concentration, current density, retention time chloride in cell (flow rate), initial pH inlet solution) form determined by central composite design (CCD). influence variables statistically significant, contributions flow rate, pH, density were found be 37.2%, 33.59%, 18.28%, 10.93%, respectively. A mathematical model established predict optimize operating conditions fenobucarb removal NaCl electrolysis process. transformation products (seven compound structures) detected liquid chromatography coupled high-resolution mass spectrometry (LC–HRMS). results indicated that degraded due direct oxidation on electrode surface, indirectly other radicals during
